Oracle often disconnects ____oracle

For some reason, Oracle on the old computer is often disconnected, and the newly bought computer is normal, and all three-party software that connects to Oracle is disconnected, like pl/sql.

So, I wonder what the cause is.

1, here to cite a modified profile blog, http://blog.csdn.net/gysheng2/article/details/6761201, however, I suggest here, if you do not have a set of Oracle changes, So it should not be caused by the frequent Oracle drop line, first look at the following several simple reasons.

2, anti-virus software or firewalls caused by, I use 360, can be sure, 360 will not cause this problem, such as Kabbah kill soft, try to shut down the service, the firewall to try.

3, the network is not stable. There are a number of possibilities, such as network problems, drivers, or protocol problems, and I am the driver of the problem, and Oracle loses contact with the listener every time the network is dropped. If it is a network problem, that can't, change a carrier. If it is a network problem driven by a driver like me, try using the Driver Wizard Update driver or download a new drive on the website.

PS: such as flash message client, is quite unstable.
